We have a huge bass amp, not sure the exact watts on it, but it has a bass input and an "instrument" input and it is plenty loud and quality. We've been putting a guitar or my synth in through it as well. We also have quite a few various amps, probably between the three of us 5 or 6 amps. None of them are big enough for small gigging though, except the largest one which is 50W...but it sounds like crap.
SO, today we go to the guitar center sale to try to find some kind of solution for our sound problem. I end up getting a Roland 40W Keyboard Amp, after being assured it was good to go for small gigs. So we head home and jam, and The 40W is plenty loud enough but it cracks obnoxiously at high volumes. I looked it up and apparently this is a problem with all of these amps, not just mine. So I'm going back tomorrow to get my $180 or so.
Anyway. We're looking for some kind of speaker setup to fix all of our problems. I was thinking we should just get a PA system, and run everything but the bass through that. After a little bit of saving I'm sure we could find a decent system on craigslist. If you dont think this is the right solution for our problem please let me know what you'd do.
My friend got a bunch of old sound equipment when he was working last summer, and I just got around to trying to sell it. But while researching all of the stuff, I thought some of it may be worth keeping and using. Particularly the DBX 900. If someone could take a look at all of this stuff and let me know if any of it is practical for our situation, I would appreciate it. I know that some of it (the huge yamaha mixer) isnt what we should be looking for. But some of the stuff I cant find much info on online so I figured somebody on a sound forum might be able to help me out. Again it would be much appreciated
